The gallium atoms will gain kinetic energy.
The gallium atoms will gain kinetic energy.
The gallium atoms will increase in temperature.
The gallium atoms will increase in temperature.
The gallium atoms will be moving faster on average.
The gallium atoms will be moving faster on average.
The gallium atoms will gain potential energy, moving freely from each other.
The gallium atoms will gain potential energy, moving freely from each other.
All of the above changes will occur on a microscopic level when the gallium in the image is melting in the person's hand.
The correct response is:
- The gallium atoms will gain kinetic energy:
As the gallium melts, the atoms will gain kinetic energy, leading to an increase in movement.
- The gallium atoms will increase in temperature:
The gain in kinetic energy will result in an increase in temperature of the gallium atoms.
- The gallium atoms will be moving faster on average:
With the increase in kinetic energy, the gallium atoms will move faster on average.
- The gallium atoms will gain potential energy, moving freely from each other:
As the gallium melts, the atoms gain potential energy and are able to move more freely from each other. This allows the gallium to change its state from a solid to a liquid.
